SQM Cement Wirewound Resistor 2W-10W
SQM Cement Wirewound Resistor feature ideal specifications for high volume and high-temperature applications. Frequently used in power supplies, motor controllers, and automotive applications, these products can be custom tailored to individual needs.
With the extended resistance range and high-temperature rating, the resistors can be specified for operation in harsh environments. SQM wirewound feature a resistance range from 0.05Ω to 1KΩ, while SQM film resistors have a resistance range of 100Ω to 150KΩ.
Standard tolerances for both devices are to ±5%, with TCRs of ±300ppm/°C and above.
